Two core motivational systems have been conceptualized as underlying emotion and behavior. The approach system drives the organism toward stimuli or events in the environment, and the avoidance system instead deters the organism away from these stimuli or events. This approach—avoidance dichotomy has been central to theories of emotion. Advances in neuroscience complementing well-designed behavioral experiments have begun to elucidate the neural mechanisms underlying approach—avoidance motivation, suggesting that these two systems exist in parallel and are lateralized in the brain. This (...) review explores the notion of approach—avoidance and the cerebral lateralization of these motivational tendencies. (shrink)

Rutherford and Lindell (2011) review the theoretical and empirical research conceptualizing emotion and emotional processing within an approach-avoidance framework. This is accompanied by an extensive discussion of the cerebral lateralization of approach-avoidance. Berntson, Norman, and Cacioppo (2011) extend this discussion by presenting a bivariate evaluative model of emotion which adopts a valence-based (positive, negative) dictum. Here we discuss this latter model in the context of an approach-avoidance perspective.

A variety of studies show that parental absence early in life leads to deleterious effects on the developing CNS. This is thought to be largely because evolutionary-dependent stimuli are necessary for the appropriate postnatal development of the young brain, an effect sometimes termed the “experience-expectant brain,” with parents providing the necessary input for normative synaptic connections to develop and appropriate neuronal survival to occur. Principal among CNS systems affected by parental input are the monoamine systems. In the present study,N= 434 (...) rhesus monkeys (233 males, 201 females) were reared in one of two conditions: as mother-reared controls (MR;n= 269) or without adults with 24-h access to same-aged peers (PR;n= 165). When subjects were six-months-old, they underwent a separation paradigm involving 4, sequential, four-day social separations from their mothers or peers, with each separation followed by three-day reunions with their mothers or their peers. Prior to the separation paradigm, baseline cisternal CSF samples were obtained, as well as at the end of each the four social separations, and after final separation, during a recovery period. CSF was assayed for concentrations of monoamine metabolites and a blood sample was genotyped for the serotonin transporter (5-HTT) genotype. Replicating earlier landmark findings, PR subjects with thesallele exhibited lower baseline concentrations of the serotonin metabolite 5-hydroxyindoleacetic acid (5-HIAA), when compared to PR subjects homozygous for theLallele. MR subjects were undifferentiated by genotype. PR subjects exhibited lower CSF 5-HIAA concentrations during baseline, but higher CSF 5-HIAA during social separations, when compared to MR subjects. There were rearing effects for the dopamine metabolite homovanillic acid (HVA) and for the norepinephrine metabolite 3-methoxy-4-hydroxyphenylglycol (MHPG), with PR subjects showing higher HVA and lower MHPG when compared to MR subjects. These findings indicate that there are long-term deficits in the response of monoamines following early maternal absence. The results of this study confirm and extend earlier findings that early parental absence has deleterious consequences for the development of the monoamine systems, and that these consequences are modulated by the 5-HTT genotype.

We examined whether differences in climate-friendly choices between the supporters of left-wing and right-wing ideologies are based on different moral foundations. Moreover, we compared general and issue-specific endorsement of moral foundations applied to climate change. Study 1 examined the endorsement of general moral foundations of university students living in Finland. Individualizing foundations were associated with increased climate-friendly choices and binding foundations were associated with decreased climate-friendly choices; the endorsement of moral foundations made the effect of political orientation disappear. In Study (...) 2 we developed and tested an issue-specific measure of moral foundations. The issue-specific endorsement of both types of foundations was directly associated with increased climate-friendly consumption. Binding foundations were associated with the avoidance of climate-friendly choices through right-wing orientation. These findings increase our understanding of differences between general and issue-specific moral concerns and their association to political orientation and pro-environmental behavior. (shrink)

The assumptions of Kohlberg, Turiel and Shweder regarding the features of moral reasoning were compared empirically. The moral reasoning of Finnish Evangelical Lutheran, Conservative Laestadian and non‐religious adolescents was studied using Kohlberg’s Moral Judgment Interview and Turiel Rule Transgression Interview methods. Religiosity and choice in moral dilemmas (orientation) were related to the structural stages of reasoning. The choice in moral dilemmas was related to the distinction between morality and social convention as separate domains. Religious participants made no distinction between morality (...) and social convention, and their conception of morality was dependent on religious authorities. The implications of the results for moral education in schools are briefly discussed. (shrink)

One of the major benefits of interdisciplinary research is the chance to swap tools between fields, to save having to reinvent the wheel. The fields of language evolution and evolutionary biology have been swapping tools for centuries to the enrichment of both. Here I will discuss three categories of tool swapping: conceptual tools, where analogies are drawn between hypotheses, patterns or processes, so that one field can take advantage of the path cut through the intellectual jungle by the other; theoretical (...) tools, where the machinery developed to process the data in one field is adapted to be applied to the data of the other; and analytical tools, where common problems encountered in both fields can be solved using useful tricks developed by one or the other. I will argue that conceptual tools borrowed from linguistics contributed to the Darwinian revolution in biology; that theoretical tools of evolutionary change can in some cases be applied to both genetic and linguistic data without having to assume the underlying evolutionary processes are exactly the same; and that there are practical problems that have long been recognised in historical linguistics that may be solved by borrowing some useful analytical tools from evolutionary biology.

The word “gene” means different things to different people, and can even be used in multiple ways by the same individual. In this review, I follow a particular thread running through Griffith and Stotz’s “Genetics and Philosophy: an introduction”, which is the way that methods of investigation influence the way we define the concept of “gene”, from nineteen century breeding experiments to twenty-first century big data bioinformatics. These different views lead to a set of gene concepts, which only partially overlap (...) each other, each of which picks up on a different part of gene behaviour, function or scientific utility. This plurality of concepts carries over to the use of the concept of “information” in biology, where the non-overlapping concepts can be connected to whether you view the genome as a blueprint for development, a response to environmental triggers, an engine of heritability, or a document of history.

This chapter is concerned with the Cambrian explosion. It considers only one particular kind of explanation for the Cambrian radiation: that major innovations in animal body plan were produced from relatively few genetic changes of large phenotypic effect. It investigates the developmental genetic hypothesis of the origin and maintenance of body plans. This chapter suggests that the genetic architecture underlying body plans was not set during the Cambrian and has been immutable since. It shows that the link between body plan (...) and phylum can become blurry when the minor phyla are considered. (shrink)

“ The Origins of Genome Architecture ” by Michael Lynch (2007) may not immediately sound like a book that someone interested in the philosophy of biology would grab off the shelf. But there are three important reasons why you should read this book. Firstly, if you want to understand biological evolution, you should have at least a passing familiarity with evolutionary change at the level of the genome. This is not to say that everyone interested in evolution should be a (...) geneticist or a bioinformatician, but that a working knowledge of genetic change is an essential part of the intellectual toolkit of modern evolutionary biology, even if your primary focus is the evolution of behaviour or the diversity of communities. Secondly, this book provides excellent examples of another important tool in the biologist’s intellectual toolkit, but one that is rarely explained or illustrated to such an extent: null (or neutral) models. The role null models play in testing hypotheses in evolution is a central focus of this book. Thirdly, as an accomplished work of advocacy for a strictly microevolutionary view of evolution, this book provides grist for the mill for the important debate about whether population genetic processes are the sine qua non of evolutionary explanations.

Phylogenies are increasingly being used to investigate human history, diversification and cultural evolution. While using phylogenies in this way is not new, new modes of analysis are being applied to inferring history, reconstructing past states, and examining processes of change. Phylogenies have the advantage of providing a way of creating a continuous history of all current populations, and they make a large number of analyses and hypothesis tests possible even when other forms of historical information are patchy or nonexistent. In (...) common with approaches taken in other historical sciences, phylogenetics is a way of reconstructing past and processes using the traces left in the present day. Trees, based on DNA, language, cultural traits, or other evidence, are now sprouting all over the academic landscape. The increasing use of phylogenetic analysis to understand human cultural evolution has been embraced by some, and scorned by others. The purpose of this article is not to review methods and applications of phylogenetic analyses, nor to consider the growing field of cultural phylogenetics, but, more broadly, to explore how we interpret phylogenies as narratives about human diversification. The first half of the article deals with meaning: phylogenies are often interpreted as histories, but a bifurcating tree is at best an abstract representation of history, and its connections to past events and processes is dependent on the data used, the assumptions made in the analysis, and the degree to which nodes in the tree (where one lineage splits into two) can be connected to change and movement in real populations. The second half of the article explores the purpose of phylogenies: a tree does not have to be a literal history of human lineages in order to be useful for investigating processes of human diversification. Phylogenies should not be read as accurate records of history, but as a way of exploring plausible explanations for current patterns of diversity. Phylogenies provide important information that can be used to test ideas about human diversity, and can help to guard against errors of inference arising from statistical artifacts. (shrink)

Does biology have general laws that apply to all levels of biological organisation, across all evolutionary time? In their book “Biology’s first law: the tendency for diversity and complexity to increase in evolutionary systems” (2010), Daniel McShea and Robert Brandon propose that the most fundamental law of biology is that all levels of biological organisation have an underlying tendency to become more complex and diverse over time. A range of processes, most notably selection, can prevent the expression of this tendency, (...) but they predict that, on average, we should see that lineages tend toward greater diversity and complexity, driven by fundamentally neutral processes. Their hypothesis can be summarised as “diversity is easy, stasis is hard”. Here, I consider evidence for this “zero force evolutionary law”. It provides a fair description of evolutionary change at the genomic level, but the predictions of the proposed law are not met for broad scale patterns in the evolution of the animal kingdom.

The extended reliance on media can be seen as one indicator of mediatization. But even though we can assume that the pervasive character of digital media essentially changes the way people experience everyday life, we cannot take these experiences for granted. There has recently been a formulation of three tasks for mediatization research; historicity, specificity and measurability, needed to empirically verify mediatization processes across time and space. In this article, we present a tool designed to handle these tasks, by measuring (...) the extent to which people experience that media reach into the deeper layers of daily human life. The tool was tested in an empirical study conducted in Sweden in 2017. The results show that perceived media reliance is played out in relation to three types of basic desires: (1) (re)productive desires, (2) recognition desires, and (3) civic desires, and is socially structured and structuring. We argue this tool, in diachronic analyses, can measure one important aspect of mediatization. (shrink)

This note investigates the class of finite initial segments of the cumulative hierarchy of pure sets. We show that this class is first-order definable over the class of finite directed graphs and that this class admits a first-order definable global linear order. We apply this last result to show that FO = FO.

This Article examines the ways in which market vendors in Kampala, Uganda, responded to plans to redevelop their markets through the concession of long-term leases to private investors. These plans met with massive resistance from the marketers, with significant outcomes. The Article uncovers how the marketers actively negotiated a “gray space” between legality and illegality and creatively used the law, with a view to asserting themselves as the legitimate rulers of their markets. It shows how the marketers engaged in highly (...) diverse modalities of struggle, stretching across the legal/illegal boundary. They organized in multiple configurations which were flexible, hybrid and mutant in character, rather than being fixed in particular organizational categories. In their struggles, the marketers engaged in shifting alliances and with a disparate range of political allies. Their politics were fluid, untamed and pragmatic, but also contradictory and fractured. This flexibility and pragmatism enabled them to navigate a complex political landscape and to make instrumental use of a generally unfavorable legal environment. (shrink)

This study is an investigation of the predictors of young people's interest in environmental political action. Data were collected by means of a survey of young people (ages 15-30) living in Finland (N = 512). The results supported the Environmental Political Action Interest Model (EPAIM) proposed in this study and show that post-materialist values and political competence increased interest in environmental political action. In addition, trust in political parties and nongovernmental organisations was indirectly associated with interest in environmental political action. (...) The results suggest how political authorities might develop policies to encourage young people's participation in environmental politics. (shrink)

We explored the relationship between materialism, awareness of environmental consequences and environmental philanthropic behaviour with a web survey (n=2,079) targeted at potential donors living in Finland. Environmental philanthropic behaviour comprise of donations of money and/or time to environmental charities. The awareness of environmental consequences was divided into egoistic, altruistic and biospheric concerns. Biospheric and egoistic concerns were positively, while materialism was negatively related to environmental philanthropic behaviour. Materialism was related to preference of charismatic species when choosing a target for donation. (...) The results have implications for conservation marketing emphasising the importance of taking the different donor segments into account. (shrink)

The aim of the study was to describe and compare whether women who used the pill or condoms discussed the choice of contraceptive method with their partner, and their sexual activity and interaction with their partner. It also studied women's thoughts about the attitudes of their partner and close others concerning unplanned pregnancy and abortion. A total of 134 women, aged 23-29, who had a stable partner relationship, answered three questionnaires. The contraceptive pill was used by 94 of the women (...) and 40 used condoms. The results show that most women discussed and planned choice and use of contraceptive method with their partner. However, more women whose partner used the condom discussed and talked about the use of the contraceptive method than women who used the pill. Independent of the contraceptive method, the women stated that non-agreement with the partner about the method resulted in no intercourse. More women who used the pill reported that they sometimes forgot to use it compared to women who used the condom. This latter group also stated to a higher degree that unplanned pregnancy would result in positive attitudes on the part of their partner and close others. (shrink)
